[0052] See Figure 1 and Figure 2 , a refrigerator according to a preferred embodiment of the present utility model, comprising: a box body and an ice-making chamber assembly 200.

[0053] The box body includes an outer shell and an inner liner 100 disposed inside the outer shell; the inner liner 100 has a liner opening 110 for mounting a box door.

[0054] An installation space is formed between the outer shell and the inner liner 100 for installing other component structures of the refrigerator and forming a foamed heat-insulating layer. A refrigeration chamber is formed inside the inner liner 100, that is, a refrigerating chamber, a variable-temperature chamber or a freezing chamber.

[0055] The box door is disposed at the liner opening 110 of the inner liner 100, and by controlling the opening and closing of the box door, the opening and closing of the refrigeration chamber can be controlled.

[0056] The refrigerator has a refrigeration cycle system for cooling the liner 100. The refrigeration cycle system generally includes component structures such as a compressor, a condenser, a dryer filter, a capillary tube, and an evaporator connected through the refrigeration cycle pipeline. The operation of the refrigeration cycle system includes a compression process, a condensation process, a throttling process, and an evaporation process. Specifically, in the compression process: after the power cord of the refrigerator is plugged in and the contacts of the thermostat are closed, the compressor starts to work. The low-temperature and low-pressure refrigerant from the evaporator is sucked into the compressor and compressed into a high-temperature and high-pressure superheated gas in the compressor cylinder and then discharged into the condenser. In the condensation process: the high-temperature and high-pressure refrigerant gas dissipates heat through the condenser, and the temperature continuously drops, gradually being cooled into a normal-temperature and high-pressure saturated vapor, and further cooled into a saturated liquid with the temperature no longer dropping. The pressure of the refrigerant hardly changes during the entire condensation process. In the throttling process: the condensed refrigerant saturated liquid flows into the capillary tube after being filtered of moisture and impurities by the dryer filter, and is throttled and depressurized through the capillary tube, and the refrigerant becomes a normal-temperature and low-pressure wet vapor. In the evaporation process: the normal-temperature and low-pressure wet vapor enters the evaporator and starts to absorb heat for vaporization, reducing the temperature of the evaporator and its surroundings, enabling the refrigeration chamber to achieve refrigeration, and turning the refrigerant into a low-temperature and low-pressure gas. The refrigerant coming out of the evaporator returns to the compressor again, repeating the above process. Through the state change of the refrigerant for energy conversion, the heat inside the refrigerator is transferred to the air outside the box, thereby realizing the refrigeration cycle of the refrigerator. When the evaporator is provided on the wall of the refrigeration chamber, it is a direct-cool refrigerator; when the evaporator is provided in the air duct of the refrigerator, it is an air-cooled refrigerator. The above structural settings and operating principles of the refrigerator refrigeration cycle system are all prior arts, and will not be elaborated in this application.

[0057] Please refer to Figure 3 and Figure 4 , the ice-making chamber assembly 200 includes a housing 210 and an ice-making unit 220 disposed inside the housing 210. The housing 210 includes a first half-shell 211 and a second half-shell 212. The first half-shell 211 and the second half-shell 212 are detachably connected. The first half-shell 211 is detachably connected to the inner wall of the liner 100, and the ice-making unit 220 is installed on the first half-shell 211.

[0058] The ice-making unit 220 is used to produce ice cubes. The first half-shell 211 and the second half-shell 212 jointly define an ice-making chamber, and the ice-making chamber is separated from the refrigeration chamber.

[0059] The cooling capacity of the ice-making chamber assembly 200 can be provided by a self-contained refrigeration pipe, which is connected to the refrigeration cycle pipeline to cool the ice-making chamber. Alternatively, a part of the refrigeration cycle pipeline extends into the ice-making chamber assembly 200 to cool the ice-making chamber.

[0060] The ice-making unit 220 includes an ice tray, and a water pipe for supplying water to the ice tray. The direct cooling section exchanges heat with the ice tray. After the water in the ice tray freezes, the driving device drives the ice tray to flip so that the opening of the ice tray faces downward for ice removal. A storage box is usually arranged below the ice tray, and the ice cubes falling off from the ice tray are stored in the storage box. The refrigeration pipe exchanges heat with the air in the ice-making chamber, which can also ensure a low-temperature state in the storage box. Thereafter, the ice tray resets, and the water pipe adds water to the ice tray to repeat the ice-making process.

[0061] When installing the ice-making chamber assembly 200, first install the first half shell 211 with the ice-making unit 220 installed on the inner wall of the cabinet liner 100, and then install the second half shell 212 on the first half shell 211.

[0062] When disassembling the ice-making chamber assembly 200, first disconnect the second half shell 212 from the first half shell 211, and then disconnect the first half shell 211 with the ice-making unit 220 installed from the inner wall of the cabinet liner 100.

[0063] In this embodiment, with such a structure, the ice-making unit 220 is installed together with the first half shell 211 to form an integral component. This component is installed as a whole on the cabinet liner 100, and then the second half shell 212 is installed on the first half shell 211. Thus, there is no need to disassemble and assemble parts one by one as in the prior art, realizing the modular installation of the ice-making chamber assembly 200, reducing the assembly difficulty, and simplifying the operation.

[0064] The first half shell 211 includes a half shell body 2114 and a back plate 2115 connected to each other. The half shell body 2114, the back plate 2115, and the second half shell 212 jointly form the housing 210, and the back plate 2115 is detachably connected to the inner wall of the cabinet liner 100.

[0065] The half shell body 2114 mainly provides the top of the ice-making chamber and a side wall close to the inner wall of the cabinet liner 100, and the back plate 2115 provides the rear wall of the ice-making chamber. The back plate 2115 is connected to the cabinet liner 100, and the half shell body 2114 is also connected to the cabinet liner 100.

[0066] The first half shell 211 is composed of two parts: the half shell body 2114 and the back plate 2115. Since the ice-making chamber assembly 200 in this embodiment is disposed at a corner on the top of the inner container 100, the back plate of the ice-making chamber assembly 200, that is, the back plate 2115, is arranged corresponding to the back plate 115 of the inner container 100, and one side wall of the ice-making chamber assembly 200, that is, one side wall of the half shell body 2114, is arranged corresponding to the side wall of the inner container 100.

[0067] The half shell body 2114 is a side wall and a top wall of the ice-making chamber assembly 200. The half shell body 2114 is connected to the back plate 2115 to form an open state of the first half shell 211. The second half shell 212 is a side wall and a bottom wall of the ice-making chamber assembly 200. The half shell body 2114, the back plate 2115, and the second half shell 212 form the outer wall of the ice-making chamber assembly 200.

[0068] In some embodiments, please refer to Figure 5 and Figure 6 , the refrigerator further includes a fixing plate 230. The fixing plate 230 is disposed between the inner container 100 and the outer shell. The fixing plate 230 has a first card slot 231 opening towards the inner container 100; a through hole corresponding to the first card slot 231 is provided on the inner container 100, and a first buckle 2111 is provided on the first half shell 211. The first buckle 2111 passes through the through hole and is clamped with the first card slot 231.

[0069] Before installing the first half shell 211, the fixing plate 230 is disposed between the inner container 100 and the outer shell. The fixing plate 230 can be fixed to the outer wall of the inner container 100 by screws. The fixing plate 230 is equivalent to being buried in the foaming layer between the inner container 100 and the outer shell.

[0070] The first buckle 2111 is provided on the half shell body 2114. The first buckle 2111 is clamped with the first card slot 231 to install the half shell body 2114 on the inner wall of the inner container 100. The back plate 2115 is also installed on the inner wall of the inner container 100. Since the ice-making unit 220 is disposed on the first half shell 211, the first half shell 211 needs to have a certain load-bearing capacity. By respectively setting connection positions on the half shell body 2114 and the back plate 2115, the ice-making chamber assembly 200 can be stably installed.

[0071] In some embodiments, the cabinet liner 100 further includes: a junction box 120 disposed on a side wall or a rear wall of the cabinet liner 100; a first opening 2112 is provided on the first half shell 211, and the junction box 120 passes through the first opening 2112 and enters the interior of the housing 210. The top wall of the junction box 120 abuts against at least a part of the edge of the first opening 2112, so that the junction box 120 supports the first half shell 211.

[0072] The junction box 120 is also pre-installed on the cabinet liner 100 before installing the ice-making chamber assembly 200. By providing the first opening 2112, at least a part of the junction box 120 extends into the ice-making chamber and functions to support the first half shell 211.

[0073] In this embodiment, the junction box 120 is disposed on the side wall of the cabinet liner 100, and the first opening 2112 is provided on the half shell body 2114.

[0074] By arranging the position of the junction box 120 in this way, the junction box 120, the fixing plate 230, and the back plate 2115 can jointly support the first half shell 211, so that the first half shell 211 is more stably installed on the cabinet liner 100.

[0075] In some embodiments, please refer to Figure 7 , a support portion 240 is provided on the cabinet liner 100 and is disposed on a side wall or a rear wall of the cabinet liner 100. A second opening 2113 is provided on the first half shell 211, and the support portion 240 passes through the second opening 2113 and enters the interior of the housing 210. The top wall of the support portion 240 abuts against at least a part of the edge of the second opening 2113, so that the support portion 240 supports the first half shell 211.

[0076] In this embodiment, the support portion 240 is a convex block protruding from the inner wall of the cabinet liner 100, and the support portion 240 supports the first half shell 211 by inserting into the second opening 2113. In this embodiment, the second opening 2113 is provided on the back plate 2115.

[0077] Thus, the support portion 240, the junction box 120, and the fixing plate 230 can all support the first half shell 211, sharing the gravity of the ice-making chamber assembly 200 to ensure that the first half shell 211 is more stably installed on the cabinet liner 100, so that the ice-making chamber assembly 200 can be stably installed on the cabinet liner 100.

[0078] Please refer to Figures 8 - 10, a first track groove 2116 with a lateral opening is provided at the edge of the first half shell 211, and a first slide rail 2121 slidably connected to the first track groove 2116 is provided at the edge of the second half shell 212. The bottom of the first slide rail 2121 abuts against the groove wall of the first track groove 2116 so that the first track groove 2116 supports the first slide rail 2121.

[0079] When installing the second half shell 212 onto the first half shell 211, align the first slide rail 2121 with the first track groove 2116, and then slide the second half shell 212 towards the back panel 2115 direction so that the second half shell 212 is installed on the first half shell 211.

[0080] Since the bottom of the first slide rail 2121 abuts against the groove wall of the first track groove 2116, the structures of the first slide rail 2121 and the first track groove 2116 can support the second half shell 212 and maintain the installation state of the second half shell 212 and the first half shell 211. In this embodiment, no structures such as the ice making unit 220 are installed on the second half shell 212, so the requirement for load bearing is not high. Therefore, even if the second half shell 212 is not directly connected to the box liner 100, the overall stability of the ice making chamber assembly 200 can still be ensured.

[0081] A second track groove 2122 is further provided at the edge of the second half shell 212, and a second slide rail 2117 slidably connected to the second track groove 2122 is provided at the edge of the first half shell 211. The extending directions of the first slide rail 2121 and the second slide rail 2117 are parallel to each other and point to the liner opening 110.

[0082] The second track groove 2122 and the second slide rail 2117 can also play a role in assisting the installation of the second half shell 212 on the first half shell 211, facilitating the connection between the first half shell 211 and the second half shell 212.

[0083] Of course, it is also possible to set the second track groove 2122 on the first half shell 211 and the second slide rail 2117 on the second half shell 212.

[0084] In this embodiment, the second half shell 212 includes an inner shell wall 2123 and an outer shell wall 2124. The inner shell wall 2123 and the shell wall form the second half shell 212 with a hollow structure, and an anti overflow part is provided at at least a part of the connection between the inner shell wall 2123 and the outer shell wall 2124.

[0085] The hollow structure formed by the inner shell wall 2123 and the outer shell wall 2124 is used to arrange the foaming layer. Since there may also be a temperature difference between the ice-making chamber and the refrigeration chamber in the box liner 100, in order to ensure the temperature stability in the ice-making chamber, it is necessary to minimize the heat exchange between the inside and outside of the ice-making chamber.

[0086] In this embodiment, the ice-making chamber assembly 200 is arranged at a corner of the box liner 100. Therefore, it is only necessary to arrange a foaming layer on the second half shell 212 where the air inside the ice-making chamber and the refrigeration chamber comes into contact, and the first half shell 211 that directly contacts the box liner 100 may not be provided with a foaming layer.

[0087] The setting of the anti-overflow part can prevent the foaming liquid from flowing out of the second half shell 212.

[0088] In this embodiment, the first track groove 2116, the first slide rail 2121, the second track groove 2122 and the second slide rail 2117 together form at least a part of the anti-overflow part.

[0089] The first track groove 2116 and the second track groove 2122 are adjacent in position. After the second half shell 212 is installed on the first half shell 211, the first track groove 2116, the first slide rail 2121, the second track groove 2122 and the second slide rail 2117 form a labyrinth structure, thus preventing the foaming liquid from overflowing. That is to say, the first track groove 2116 and the first slide rail 2121 not only facilitate the installation of the second half shell 212, but also can support the second half shell 212 and can also prevent the foaming liquid from overflowing as a part of the anti-overflow part.

[0090] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
